“Thermo barrier protection, so that causes you to sweat a lot especially during a run like this,” Grover said. “This is going be more mental toughness because I'm sure after the first half of the marathon, I'll be like, “Why did I do this?’ but I'll have to just stay tough about it.”

After all, it's for a good cause.

Grover wanted to do something to help the community, so he found the Genesis House, which provides temporary housing and help for young or expectant mothers. But it needs help of its own.

Some recent rain flooded the basement. The house also needs a new furnace and roofing on the 80-year-old building.

Executive director Maggie Graff said Grover's fundraising on a GoFundMe page for the marathon will go toward about $10,000 worth of repairs.

“Just so blessed by his young heart to not only give back to the community, but to choose a struggling organization that receives no federal or state help,” Graff said.

Graff knows Grover’s feat is no easy task, but they will be there cheering him on along the way.
